bphR1-RBS-RFP-Terminator
This part is composed by bphR1 promoter (BBa_K1155001), from Pseudomonas pseudoalcaligenes KF707, which allows the transcription of the genes of biphenyl degradation, the RBS (BBa_B0034), RFP gene (BBa_E1010) and terminator (BBa_B0015). In our project, genes of degradation was replaced by RFP gene to detect the compound.

Figure 1: Schema of BBa_K1413024 construction.

Mechanism explanation: In absence of PCBs, bphR2 (BBa_K1413021) is bound to bphR1 promoter which activate the transcription of RFP but in very low expression. In presence of PCBs, when compound diffuses into the media, it binds to bphr2 protein which undergoes a conformational change that permits to activate more stronger bphR1 promoter and increase the transcription of RFP.
